2 Claims. (Cl. E's-59) The present invention relates to new and usefulim-- provements in chimney caps and has for its primary object toprovide, in a manner as hereinafter set forth, a device of thischaracter comprising novel means for positively excluding the elements,when desired, also animals, birds, etc., from a chimney.

Another very important object of the invention is to provide, in achimney cap of the type including a stack and a swinging cover, novelmeans for pivotally mounting said cover on said stack.

Other objects of the invention are to provide a chimney cap of thecharacter described which will be comparatively simple in construction,strong, durable, compact, attractive in appearance and which may bemanufactured and installed at low cost.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the ac companying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

Figure l is a perspective view of a chimney cap constructed inaccordance with the present invention, showing the device installed;

Figure 2 is a view in vertical section through the upper portion of thedevice, taken substantially on the line 22 of Figure 1; and

Figure 3 is a vertical sectional view through one of the cover pivots,taken substantially on the line 3-3 of Figure 1.

Referring now to the drawing in detail, it will be seen that theembodiment of the invention which has been illustrated comprises asubstantially square metallic stack 4 of suitable dimensions which isadapted to be secured vertically on the upper end or top of aconventional chimney, as indicated at 5. At its upper end, the stack 4terminates in an inturned flange 6.

Pivotally mounted for swinging movement in a vertical plane on the stack4 and adapted to seat when in closed position on the flanged upper end 6thereof is a hood or cover 7 of suitable metal. The cover 7 straddlesthe stack 4, said cover including right angularly bent side flanges 8which receive said stack therebetween.

Pivots 9 in the rear end portions of the flanges 8 secure the cover 7 onthe stack 4. As shown to advantage in Figure 3 of the drawing, thepivots 9 comprise headed, threadedly connected male and female bolts 10and 11, respectively. The stack 4 and the flanges 8 are provided,respectively, with aligned, circular openings 12 and 13 which receivethe female bolt 11.

Mounted on the bolts 11, between the stack 4 and the flanges 8, are coilsprings 14. One end portion of the coil springs 14 are anchored inapertures provided therefor in the stack 4, as indicated at 15. At theirother ends, the coil springs 14 terminate in hooks 16 which are engagedbehind the rear ends of the flanges 8 for yieldingly urging the cover 7toward closed position on the stack 4.

Mounted on the rear end portion of the cover 7 is a metallic bracket 17.A pull chain or cable 18 has one end connected to the bracket 17.

It is thought that the operation of the invention will be readilyapparent from a consideration of the foregoing. Briefly, the tensionedcoil springs 14 normally retain the cover 7 in closed position on thetop 6 of the stack 4 with the assistance of gravity. Thus, the top ofthe chimney 5 is tightly closed for excluding the elements, birds,animals, etc. To open the chimney when desired, the cover 7 is swungupwardly, rearwardly and downwardly to the broken line position ofFigure 1 of the drawing against the tension of the springs 14 throughthe medium of the pull chain or cable 13 in an obvious manner. The chainor cable 18 may be secured in any suitable manner. Also, the chain orcable 18 may be operated either from the interior or the exterior of thecabin, house or other building. Of course, when the chain or cable 18 isreleased the cover 7 is returned to closed position on the stack 4 bythe springs 14.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents maybe resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A chimney cap of the character described comprising: a stack open atits upper end, said stack for mounting on top of a chimney, a cover forsaid upper end of said stack, said cover including angularly bent sideflanges receiving the stack therebetween, said stack and side flangeshaving aligned openings therein, pivots engaged in the aligned openingsfor mounting the cover on the stack for vertical swinging movement, saidpivots including headed, threadedly connected male and female boltsextending through the openings, means for manually swinging the cover toopen position, and means for closing said cover comprising springsterminally attached to opposite sides of said stack and having hookedends hooking over edges of said flanges.

2. A chimney cap of the character described comprising: a stack open atits upper end, said stack for mounting on top of a chimney, a cover forsaid upper end of said stack, said cover including angularly bent sideflanges receiving the stack therebetween, said stack and side flangeshaving aligned openings therein, pivots engaged in the aligned openingsfor mounting the cover on the stack for vertical swinging movement, saidpivots including headed, threadedly connected male and female boltsextending through the openings, means for manually swinging the cover toopen position, and means for closing said cover, the last-named. meanscomprising coil springs encircling the female bolts between the stackand the flanges, said coil springs being tensioned and having one endanchored to the stack and their other ends anchored to said flanges.
